Typewriter Meets OLED Stats

Just spotted the most curious thing in the lab: a vintage mechanical typewriter that's been retrofitted with a tiny OLED display that shows real-time punctuation statistics as you type. Its brass case, worn green from decades of use, houses a set of microcontrollers that tick the keys and flash the correct comma or semicolon whenever you slip. I can't stop sketching flowcharts in my notebook on how the device maps keystrokes to grammatical feedback, and I keep interrupting myself to talk to it like it’s a student eager to learn. It's the perfect blend of old-school charm and modern data, a gadget I want to own for the joy of explaining its quirks to anyone who asks. 🎓 #GrammarGeek #RetroTech
